The user right "editusercssjs" should be split into "editusercss" and "edituserjs". Javascript can be dangerous, esp. on larger wikis where there are a lot of sysops. With the right split, a higher level user (e.g., bureaucrat) could be allowed to edit .js while regular sysops could edit .css.

Also, if possible, splitting this right for the MediaWiki namespace as well would probably be a good idea, though abuse there is less likely as it usually has more eyes watching it.
